Automobile Air Conditioning

Introduction
Due to varying conditions of heating, ventilating, cooling and dehumidification in atmosphere at various places, the air conditioning of automobiles is very essential. To maintain human comfort and improve internal atmosphere in an enclosed space, proper control of freshness temperature, humidity and cleanliness of air required. In an automobile the air conditioning system involvs two main processes of heating and cooling. In the heating system, warm water..............etc

The Hy-Wire Car

Introduction
Cars are immensely complicated machines, but when you get down to it, they do an incredibly simple job. Most of the complex stuff in a car is dedicated to turning wheels, which grip the road to pull the car body and passengers along. The steering system tilts the wheels side to side to turn the car, and brake and acceleration systems control the speed of the wheels.

Given that the overall function of a car is so basic (it just needs to provide rotary motion to whe..............etc

NANOTECHNOLOGY & MECHANICAL ENGINEERING


INTRODUCTION
We live in a world of machines. And the technical foundation for these machines lies in the steam engine developed during the 1780s by James Watt. The concept of deriving useful mechanical work from raw fuel such as wood, coal, oil, and now uranium was revolutionary. Watt also developed the slider-crank mechanism to convert reciprocating motion to rotary motion.
To improve on this first, basic engine, the people who followed Watt created the science of thermodynami..............etc

Oil Drilling

Introduction
Oil and natural gas furnish about three-fourths of our energy needs, fueling our homes, work places, factories and transportation systems. Using variety of methods, on land and at sea, small crews of specialized workers search for geologic formations that are likely to contain oil and gas. Seismic prospecting - a technique based on measuring the time it takes sound waves to travel through underground formations and return to surface-has revolutionized oil and gas explora..............etc

Space Robotics

Introduction
Robot is a system with a mechanical body, using computer as its brain. Integrating the sensors and actuators built into the mechanical body, the motions are realised with the computer software to execute the desired task. Robots are more flexible in terms of ability to perform new tasks or to carry out complex sequence of motion than other categories of automated manufacturing equipment. Today there is lot of interest in this field and a separate branch of technology '..............etc
